FIELD OF INVENTION

This invention relates generally the field of soybean breeding,specifically relating to a soybean variety designated 93Y10.

BACKGROUND OF INVENTION

The present invention relates to a new and distinctive soybean variety,designated 93Y10 which has been the result of years of careful breedingand selection as part of a soybean breeding program. There are numeroussteps in the development of any novel, desirable plant germplasm. Plantbreeding begins with the analysis and definition of problems andweaknesses of the current germplasm, the establishment of program goals,and the definition of specific breeding objectives. The next step isselection of germplasm that possess the traits to meet the programgoals. The goal is to combine in a single variety an improvedcombination of desirable traits from the parental germplasm. Theseimportant traits may include but are not limited to higher seed yield,resistance to diseases and insects, tolerance to drought and heat,altered fatty acid profile, abiotic stress tolerance, improvements incompositional traits and better agronomic qualities.

These processes, which lead to the final step of marketing anddistribution, can take from six to twelve years from the time the firstcross is made. Therefore, development of new varieties is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

Soybean (Glycine max), is an important and valuable field crop. Thus, acontinuing goal of soybean breeders is to develop stable, high yieldingsoybean varieties that are agronomically sound. The reasons for thisgoal are to maximize the amount of grain produced on the land used andto supply food for both animals and humans. To accomplish this goal, thesoybean breeder must select and develop soybean plants that have thetraits that result in superior varieties.

Pioneer soybean research staff create over 500,000 potential newvarieties each year. Of those new varieties, less than 50 and morecommonly less than 25 are actually selected for commercial use.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report”, Iowa Soybean Promotion Board & American SoybeanAssociation Special Report 92S, May 1990). Changes in fatty acidcomposition for improved oxidative stability and nutrition are alsoimportant traits. Industrial uses for processed soybean oil includeingredients for paints, plastics, fibers, detergents, cosmetics, andlubricants. Soybean oil may be split, inter-esterified, sulfurized,epoxidized, polymerized, ethoxylated, or cleaved. Designing andproducing soybean oil derivatives with improved functionality,oliochemistry, is a rapidly growing field. The typical mixture oftriglycerides is usually split and separated into pure fatty acids,which are then combined with petroleum-derived alcohols or acids,nitrogen, sulfonates, chlorine, or with fatty alcohols derived from fatsand oils.

Soybean is also used as a food source for both animals and humans.Soybean is widely used as a source of protein for animal feeds forpoultry, swine and cattle. During processing of whole soybeans, thefibrous hull is removed and the oil is extracted. The remaining soybeanmeal is a combination of carbohydrates and approximately 50% protein.

For human consumption soybean meal is made into soybean flour which isprocessed to protein concentrates used for meat extenders or specialtypet foods. Production of edible protein ingredients from soybean offersa healthy, less expensive replacement for animal protein in meats aswell as dairy-type products.

FURTHER EMBODIMENTS OF THE INVENTION Genetic Marker Profile Through SSRand First Generation Progeny

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile which can identify plants of the same variety ora related variety or be used to determine or validate a pedigree.Genetic marker profiles can be obtained by techniques such asRestriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length Polymorphisms(AFLPs), Simple Sequence Repeats (SSRs) which are also referred to asMicrosatellites, and Single Nucleotide Polymorphisms (SNPs). Forexample, see Cregan et. al, “An Integrated Genetic Linkage Map of theSoybean Genome” Crop Science 39:1464-1490 (1999), and Berry et al.,Assessing Probability of Ancestry Using Simple Sequence Repeat Profiles:Applications to Maize Inbred Lines and Soybean Varieties” Genetics165:331-342 (2003), each of which are incorporated by reference hereinin their entirety.

Particular markers used for these purposes are not limited to anyparticular set of markers, but are envisioned to include any type ofmarker and marker profile which provides a means of distinguishingvarieties. One method of comparison is to use only homozygous loci for93Y10. For example, one set of publicly available markers which could beused to screen and identify variety 93Y10 is disclosed in Table 3.

Primers and PCR protocols for assaying these and other markers aredisclosed in the Soybase (sponsored by the USDA Agricultural ResearchService and Iowa State University) located at the world wide web at129.186.26.94/SSR.html. In addition to being used for identification ofsoybean variety 93Y10 and plant parts and plant cells of variety 93Y10,the genetic profile may be used to identify a soybean plant producedthrough the use of 93Y10 or to verify a pedigree for progeny plantsproduced through the use of 93Y10. The genetic marker profile is alsouseful in breeding and developing backcross conversions.

The present invention comprises a soybean plant characterized bymolecular and physiological data obtained from the representative sampleof said variety deposited with the ATCC. Further provided by theinvention is a soybean plant formed by the combination of the disclosedsoybean plant or plant cell with another soybean plant or cell andcomprising the homozygous alleles of the variety.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may bepresent. Another advantage of this type of marker is that, through useof flanking primers, detection of SSRs can be achieved, for example, bythe polymerase chain reaction (PCR), thereby eliminating the need forlabor-intensive Southern hybridization. The PCR detection is done by useof two oligonucleotide primers flanking the polymorphic segment ofrepetitive DNA. Repeated cycles of heat denaturation of the DNA followedby annealing of the primers to their complementary sequences at lowtemperatures, and extension of the annealed primers with DNA polymerase,comprise the major part of the methodology.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which may be measured by the number of basepairs of the fragment. While variation in the primer used or inlaboratory procedures can affect the reported fragment size, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing varieties it is preferable if all SSRprofiles are performed in the same lab.

Primers used are publicly available and may be found in the Soybase orCregan supra. See also, PCT Publication No. WO 99/31964 NucleotidePolymorphisms in Soybean, U.S. Pat. No. 6,162,967 Positional Cloning ofSoybean Cyst Nematode Resistance Genes, and US 2002/0129402A1 SoybeanSudden Death Syndrome Resistant Soybeans and Methods of Breeding andIdentifying Resistant Plants, the disclosure of which are incorporatedherein by reference.

The SSR profile of soybean plant 93Y10 can be used to identify plantscomprising 93Y10 as a parent, since such plants will comprise the samehomozygous alleles as 93Y10. Because the soybean variety is essentiallyhomozygous at all relevant loci, most loci should have only one type ofallele present. In contrast, a genetic marker profile of an F1 progenyshould be the sum of those parents, e.g., if one parent was homozygousfor allele x at a particular locus, and the other parent homozygous forallele y at that locus, then the F1 progeny will be xy (heterozygous) atthat locus. Subsequent generations of progeny produced by selection andbreeding are expected to be of genotype x (homozygous), y (homozygous),or xy (heterozygous) for that locus position. When the F1 plant isselfed or sibbed for successive filial generations, the locus should beeither x or y for that position.

In addition, plants and plant parts substantially benefiting from theuse of 93Y10 in their development, such as 93Y10 comprising a backcrossconversion, transgene, or genetic sterility factor, may be identified byhaving a molecular marker profile with a high percent identity to 93Y10.Such a percent identity might be 95%, 96%, 97%, 98%, 99%, 99.5% or 99.9%identical to 93Y10.

The SSR profile of 93Y10 also can be used to identify essentiallyderived varieties and other progeny varieties developed from the use of93Y10, as well as cells and other plant parts thereof. Such plants maybe developed using the markers identified in WO 00/31964, U.S. Pat. No.6,162,967 and US2002/0129402A1. Progeny plants and plant parts producedusing 93Y10 may be identified by having a molecular marker profile of atleast 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 76%, 77%,78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%,92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% genetic contributionfrom soybean variety, as measured by either percent identity or percentsimilarity. Such progeny may be further characterized as being within apedigree distance of 93Y10, such as within 1, 2, 3, 4 or 5 or lesscross-pollinations to a soybean plant other than 93Y10, or a plant thathas 93Y10 as a progenitor. Unique molecular profiles may be identifiedwith other molecular tools such as SNPs and RFLPs.

While determining the SSR genetic marker profile of the plants describedsupra, several unique SSR profiles may also be identified which did notappear in either parent of such plant. Such unique SSR profiles mayarise during the breeding process from recombination or mutation. Acombination of several unique alleles provides a means of identifying aplant variety, an F1 progeny produced from such variety, and progenyproduced from such variety.

Introduction of a New Trait or Locus into 93Y10

Variety 93Y10 represents a new base genetic variety into which a newlocus or trait may be introgressed. Direct transformation andbackcrossing represent two important methods that can be used toaccomplish such an introgression.

Backcross Conversions of 93Y10

A backcross conversion of 93Y10 occurs when DNA sequences are introducedthrough backcrossing (Hallauer et al, 1988), with 93Y10 utilized as therecurrent parent. Both naturally occurring and transgenic DNA sequencesmay be introduced through backcrossing techniques. A backcrossconversion may produce a plant with a trait or locus conversion in atleast two or more backcrosses, including at least 2 crosses, at least 3crosses, at least 4 crosses, at least 5 crosses and the like. Molecularmarker assisted breeding or selection may be utilized to reduce thenumber of backcrosses necessary to achieve the backcross conversion. Forexample, see Openshaw, S. J. et al., Marker-assisted Selection inBackcross Breeding. In: Proceedings Symposium of the Analysis ofMolecular Data, August 1994, Crop Science Society of America, Corvallis,Oreg., where it is demonstrated that a backcross conversion can be madein as few as two backcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (single genes or closely linked genes as vs.unlinked genes), the level of expression of the trait, the type ofinheritance (cytoplasmic or nuclear) and the types of parents includedin the cross. It is understood by those of ordinary skill in the artthat for single gene traits that are relatively easy to classify, thebackcross method is effective and relatively easy to manage. (SeeHallauer et al. in Corn and Corn Improvement, Sprague and Dudley, ThirdEd. 1998). Desired traits that may be transferred through backcrossconversion include, but are not limited to, sterility (nuclear andcytoplasmic), fertility restoration, nutritional enhancements, droughttolerance, nitrogen utilization, altered fatty acid profile, lowphytate, industrial enhancements, disease resistance (bacterial, fungalor viral), insect resistance and herbicide resistance. In addition, anintrogression site itself, such as an FRT site, Lox site or other sitespecific integration site, may be inserted by backcrossing and utilizedfor direct insertion of one or more genes of interest into a specificplant variety. In some embodiments of the invention, the number of locithat may be backcrossed into 93Y10 is at least 1, 2, 3, 4, or 5 and/orno more than 6, 5, 4, 3, or 2. A single locus may contain severaltransgenes, such as a transgene for disease resistance that, in the sameexpression vector, also contains a transgene for herbicide resistance.The gene for herbicide resistance may be used as a selectable markerand/or as a phenotypic trait. A single locus conversion of site specificintegration system allows for the integration of multiple genes at theconverted loci.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele requires growing and selfing thefirst backcross generation to determine which plants carry the recessivealleles. Recessive traits may require additional progeny testing insuccessive backcross generations to determine the presence of the locusof interest. The last backcross generation is usually selfed to givepure breeding progeny for the gene(s) being transferred, although abackcross conversion with a stably introgressed trait may also bemaintained by further backcrossing to the recurrent parent withselection for the converted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. The backcross is a form ofinbreeding, and the features of the recurrent parent are automaticallyrecovered after successive backcrosses. Poehiman, Breeding Field Crops,P. 204 (1987). Poehlman suggests from one to four or more backcrosses,but as noted above, the number of backcrosses necessary can be reducedwith the use of molecular markers. Other factors, such as a geneticallysimilar donor parent, may also reduce the number of backcrossesnecessary. As noted by Poehlman, backcrossing is easiest for simplyinherited, dominant and easily recognized traits.

One process for adding or modifying a trait or locus in soybean variety93Y10 comprises crossing 93Y10 plants grown from 93Y10 seed with plantsof another soybean variety that comprise the desired trait or locus,selecting F1 progeny plants that comprise the desired trait or locus toproduce selected F1 progeny plants, crossing the selected progeny plantswith the 93Y10 plants to produce backcross progeny plants, selecting forbackcross progeny plants that have the desired trait or locus and themorphological characteristics of soybean variety 93Y10 to produceselected backcross progeny plants; and backcrossing to 93Y10 three ormore times in succession to produce selected fourth or higher backcrossprogeny plants that comprise said trait or locus. The modified 93Y10 maybe further characterized as having the physiological and morphologicalcharacteristics of soybean variety 93Y10 listed in Table 1 as determinedat the 5% significance level when grown in the same environmentalconditions and/or may be characterized by percent similarity or identityto 93Y10 as determined by SSR markers. The above method may be utilizedwith fewer backcrosses in appropriate situations, such as when the donorparent is highly related or markers are used in the selection step.Desired traits that may be used include those nucleic acids known in theart, some of which are listed herein, that will affect traits throughnucleic acid expression or inhibition. Desired loci include theintrogression of FRT, Lox and other sites for site specific integration,which may also affect a desired trait if a functional nucleic acid isinserted at the integration site.

In addition, the above process and other similar processes describedherein may be used to produce first generation progeny soybean seed byadding a step at the end of the process that comprises crossing 93Y10with the introgressed trait or locus with a different soybean plant andharvesting the resultant first generation progeny soybean seed.

Transgenes

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to alter the traits of a plant in a specific manner.Any DNA sequences, whether from a different species or from the samespecies, which are inserted into the genome using transformation,backcrossing or other methods known to one of skill in the art arereferred to herein collectively as “transgenes”. In some embodiments ofthe invention, a transgenic variant of 93Y10 may contain at least onetransgene but could contain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10and/or no more than 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2.Over the last fifteen to twenty years several methods for producingtransgenic plants have been developed, and the present invention alsorelates to transgenic variants of the claimed soybean variety 93Y10.

One embodiment of the invention is a process for producing soybeanvariety 93Y10, further comprising a desired trait, said processcomprising transforming a soybean plant of variety 93Y10 with atransgene that confers a desired trait. Another embodiment is theproduct produced by this process. In one embodiment the desired traitmay be one or more of herbicide resistance, insect resistance, diseaseresistance, decreased phytate, or modified fatty acid or carbohydratemetabolism. The specific gene may be any known in the art or listedherein, including; a polynucleotide conferring resistance toimidazolinone, sulfonylurea, glyphosate, glufosinate, triazine andbenzonitrile; a polynucleotide encoding a bacillus thuringiensispolypeptide, a polynucleotide encoding phytase, FAD-2, FAD-3, galactinolsynthase or a raffinose synthetic enzyme; or a polynucleotide conferringresistance to soybean cyst nematode, brown stem rot, phytophthora rootrot, soybean mosaic virus or sudden death syndrome.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88 and Armstrong, “The First Decade of Maize Transformation: A Reviewand Future Perspective” (Maydica 44:101-109, 1999). In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

The most prevalent types of plant transformation involve theconstruction of an expression vector. Such a vector comprises a DNAsequence that contains a gene under the control of or operatively linkedto a regulatory element, for example a promoter. The vector may containone or more genes and one or more regulatory elements.

A genetic trait which has been engineered into the genome of aparticular soybean plant may then be moved into the genome of anothervariety using traditional breeding techniques that are well known in theplant breeding arts. For example, a backcrossing approach is commonlyused to move a transgene from a transformed soybean variety into analready developed soybean variety, and the resulting backcrossconversion plant would then comprise the transgene(s).

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences. Forexample, see the traits, genes and transformation methods listed in U.S.Pat. No. 6,118,055.

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants that areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem. 114: 92-6(1981).

A genetic map can be generated, primarily via conventional RestrictionFragment Length Polymorphisms (RFLP), Polymerase Chain Reaction (PCR)analysis, Simple Sequence Repeats (SSR) and Single NucleotidePolymorphisms (SNP) that identifies the approximate chromosomal locationof the integrated DNA molecule. For exemplary methodologies in thisregard, see Glick and Thompson, METHODS IN PLANT MOLECULAR BIOLOGY ANDBIOTECHNOLOGY 269-284 (CRC Press, Boca Raton, 1993).

Wang et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome”, Science,280:1077-1082, 1998, and similar capabilities are becoming increasinglyavailable for the soybean genome. Map information concerning chromosomallocation is useful for proprietary protection of a subject transgenicplant. If unauthorized propagation is undertaken and crosses made withother germplasm, the map of the integration region can be compared tosimilar maps for suspect plants to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR and sequencing, all of which areconventional techniques. SNPs may also be used alone or in combinationwith other techniques.

Likewise, by means of the present invention, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of soybean the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide resistance,agronomic, grain quality and other traits. Transformation can also beused to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to soybean as well as non-nativeDNA sequences can be transformed into soybean and used to alter levelsof native or non-native proteins. Various promoters, targetingsequences, enhancing sequences, and other DNA sequences can be insertedinto the genome for the purpose of altering the expression of proteins.Reduction of the activity of specific genes (also known as genesilencing, or gene suppression) is desirable for several aspects ofgenetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook ch.118 (Springer-Verlag 1994) or other genetic elements such as a FRT, Loxor other site specific integration site, antisense technology (see,e.g., Sheehy et al.

(1993) Antisense Res. Dev. 3:253);oligonucleotide mediated targeted modification (e.g., WO 03/076574 andWO 99/25853); Zn-finger targeted molecules (e.g., WO 01/52620; WO03/048345; and WO 00/42219); and other methods or combinations of theabove methods known to those of skill in the art.

Exemplary nucleotide sequences that may be altered by geneticengineering include, but are not limited to, those categorized below.

1. Transgenes that Confer Resistance to Insects or Disease and thatEncode:

(A) Plant disease resistance genes. Plant defenses are often activatedby specific interaction between the product of a disease resistance gene(R) in the plant and the product of a corresponding avirulence (Avr)gene in the pathogen. A plant variety can be transformed with clonedresistance gene to engineer plants that are resistant to specificpathogen strains. See, for example Jones et al., Science 266: 789 (1994)(cloning of the tomato Cf-9 gene for resistance to Cladosporium fulvum);Martin et al., Science 262: 1432 (1993) (tomato Pto gene for resistanceto Pseudomonas syringae pv. tomato encodes a protein kinase); Mindrinoset al., Cell 78: 1089 (1994) (Arabidopsis RSP2 gene for resistance toPseudomonas syringae), McDowell & Woffenden, (2003) Trends Biotechnol.21(4): 178-83 and Toyoda et al., (2002) Transgenic Res. 11 (6):567-82.

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

5. Genes that create a site for site specific DNA integration. Thisincludes the introduction of FRT sites that may be used in the FLP/FRTsystem and/or Lox sites that may be used in the Cre/Loxp system. Forexample, see Lyznik, et al., Site-Specific Recombination for GeneticEngineering in Plants, Plant Cell Rep (2003) 21:925-932 and WO 99/25821,which are hereby incorporated by reference.

Plant Breeding Techniques Development of Soybean Sublines

Sublines of 93Y10 may also be developed. Although 93Y10 containssubstantially fixed genetics, and is phenotypically uniform and with nooff-types expected, there still remains a small proportion ofsegregating loci either within individuals or within the population as awhole. Sublining provides the ability to select for these loci, whichhave with no apparent morphological or phenotypic effect on the plantcharacteristics, but do have an affect on overall yield. For example,the “breeding bias” methods described in U.S. Pat. No. 5,437,697 andU.S. patent application Ser. No. 10/901,425 may be utilized by a breederof ordinary skill in the art to identify genetic loci that areassociated with yield potential to further purify the variety in orderto increase its yield. U.S. Pat. No. 5,437,697 and U.S. patentapplication Ser. No. 10/901,425 are incorporated by reference for thispurpose. Based on these teachings, a breeder of ordinary skill in theart may fix agronomically important loci by making them homozygous inorder to optimize the performance of the variety. No crosses to adifferent variety are made, and so a new genetic variety is not createdand the overall genetic composition of the variety remains essentiallythe same. The development of soybean sublines and the use of acceleratedyield technology is a plant breeding technique.

Using 93Y10 to Develop Other Soybean Varieties

Soybean varieties such as 93Y10 are typically developed for use in seedand grain production. However, soybean varieties such as 93Y10 alsoprovide a source of breeding material that may be used to develop newsoybean varieties. Plant breeding techniques known in the art and usedin a soybean plant breeding program include, but are not limited to,recurrent selection, mass selection, bulk selection, backcrossing,pedigree breeding, open pollination breeding, restriction fragmentlength polymorphism enhanced selection, genetic marker enhancedselection, making double haploids, and transformation. Oftencombinations of these techniques are used. The development of soybeanvarieties in a plant breeding program requires, in general, thedevelopment and evaluation of homozygous varieties. There are manyanalytical methods available to evaluate a new variety. The oldest andmost traditional method of analysis is the observation of phenotypictraits but genotypic analysis may also be used.

Using 93Y10 in a Breeding Program

This invention is directed to methods for producing a soybean plant bycrossing a first parent soybean plant with a second parent soybean plantwherein either the first or second parent soybean plant is variety93Y10. The other parent may be any other soybean plant, such as asoybean plant that is part of a synthetic or natural population. Anysuch methods using soybean variety 93Y10 are part of this invention:selfing, sibbing, backcrosses, mass selection, pedigree breeding, bulkselection, hybrid production, crosses to populations, and the like.These methods are well known in the art and some of the more commonlyused breeding methods are described below. Descriptions of breedingmethods can be found in one of several reference books (e.g., Allard,Principles of Plant Breeding, 1960; Simmonds, Principles of CropImprovement, 1979; Sneep et al., 1979; Fehr, “Breeding Methods forCultivar Development”, Chapter 7, Soybean Improvement, Production andUses, 2^(nd) ed., Wilcox editor, 1987).

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such as93Y10 and another soybean variety having one or more desirablecharacteristics that is lacking or which complements 93Y10. If the twooriginal parents do not provide all the desired characteristics, othersources can be included in the breeding population. In the pedigreemethod, superior plants are selfed and selected in successive filialgenerations. In the succeeding filial generations the heterozygouscondition gives way to homogeneous varieties as a result ofself-pollination and selection. Typically in the pedigree method ofbreeding, five or more successive filial generations of selfing andselection is practiced: F1→F2; F2→F3; F3→F4; F4→F₅, etc. After asufficient amount of inbreeding, successive filial generations willserve to increase seed of the developed variety. Preferably, thedeveloped variety comprises homozygous alleles at about 95% or more ofits loci.

In addition to being used to create a backcross conversion, backcrossingcan also be used in combination with pedigree breeding. As discussedpreviously, backcrossing can be used to transfer one or morespecifically desirable traits from one variety, the donor parent, to adeveloped variety called the recurrent parent, which has overall goodagronomic characteristics yet lacks that desirable trait or traits.However, the same procedure can be used to move the progeny toward thegenotype of the recurrent parent but at the same time retain manycomponents of the non-recurrent parent by stopping the backcrossing atan early stage and proceeding with selfing and selection. For example, asoybean variety may be crossed with another variety to produce a firstgeneration progeny plant. The first generation progeny plant may then bebackcrossed to one of its parent varieties to create a BC1 or BC2.Progeny are selfed and selected so that the newly developed variety hasmany of the attributes of the recurrent parent and yet several of thedesired attributes of the non-recurrent parent. This approach leveragesthe value and strengths of the recurrent parent for use in new soybeanvarieties.

Therefore, an embodiment of this invention is a method of making abackcross conversion of soybean variety 93Y10, comprising the steps ofcrossing a plant of soybean variety 93Y10 with a donor plant comprisinga desired trait, selecting an F1 progeny plant comprising the desiredtrait, and backcrossing the selected F1 progeny plant to a plant ofsoybean variety 93Y10. This method may further comprise the step ofobtaining a molecular marker profile of soybean variety 93Y10 and usingthe molecular marker profile to select for a progeny plant with thedesired trait and the molecular marker profile of 93Y10. In oneembodiment the desired trait is a mutant gene or transgene present inthe donor parent.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. 93Y10 is suitable for use in a recurrentselection program. The method entails individual plants crosspollinating with each other to form progeny. The progeny are grown andthe superior progeny selected by any number of selection methods, whichinclude individual plant, half-sib progeny, full-sib progeny and selfedprogeny. The selected progeny are cross pollinated with each other toform progeny for another population. This population is planted andagain superior plants are selected to cross pollinate with each other.Recurrent selection is a cyclical process and therefore can be repeatedas many times as desired. The objective of recurrent selection is toimprove the traits of a population. The improved population can then beused as a source of breeding material to obtain new varieties forcommercial or breeding use, including the production of a syntheticcultivar. A synthetic cultivar is the resultant progeny formed by theintercrossing of several selected varieties.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection seeds fromindividuals are selected based on phenotype or genotype. These selectedseeds are then bulked and used to grow the next generation. Bulkselection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Also, instead of self pollination, directed pollinationcould be used as part of the breeding program.

Mutation Breeding

Mutation breeding is another method of introducing new traits intosoybean variety 93Y10. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), Beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), or ultravioletradiation (preferably from 2500 to 2900 nm), or chemical mutagens (suchas base analogues (5-bromo-uracil), related compounds (8-ethoxycaffeine), antibiotics (streptonigrin), alkylating agents (sulfurmustards, nitrogen mustards, epoxides, ethylenamines, sulfates,sulfonates, sulfones, lactones), azide, hydroxylamine, nitrous acid, oracridines. Once a desired trait is observed through mutagenesis thetrait may then be incorporated into existing germplasm by traditionalbreeding techniques. Details of mutation breeding can be found in“Principles of Cultivar Development” Fehr, 1993 Macmillan PublishingCompany. In addition, mutations created in other soybean plants may beused to produce a backcross conversion of 93Y10 that comprises suchmutation.

Breeding with Molecular Markers

Molecular markers, which includes markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs) and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing 93Y10.

Isozyme Electrophoresis and RFLPs have been widely used to determinegenetic composition. Shoemaker and Olsen, ((1993) Molecular Linkage Mapof Soybean (Glycine max L. Merr.). p. 6.131-6.138. In S. J. O'Brien(ed.) Genetic Maps: Locus Maps of Complex Genomes. Cold Spring HarborLaboratory Press. Cold Spring Harbor, N.Y.), developed a moleculargenetic linkage map that consisted of 25 linkage groups with about 365RFLP, 11 RAPD (random amplified polymorphic DNA), three classicalmarkers, and four isozyme loci.

SSR technology is currently the most efficient and practical markertechnology; more marker loci can be routinely used and more alleles permarker locus can be found using SSRs in comparison to RFLPs. For exampleDiwan and Cregan, described a highly polymorphic microsatellite loci insoybean with as many as 26 alleles. (Diwan, N., and P. B. Cregan 1997Automated sizing of fluorescent-labeled simple sequence repeat (SSR)markers to assay genetic variation in Soybean Theor. Appl. Genet.95:220-225.) Single Nucleotide Polymorphisms may also be used toidentify the unique genetic composition of the invention and progenyvarieties retaining that unique genetic composition. Various molecularmarker techniques may be used in combination to enhance overallresolution.

Soybean DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Cregan et. al, “An Integrated Genetic Linkage Map of the SoybeanGenome” Crop Science 39:1464-1490 (1999). Sequences and PCR conditionsof SSR Loci in Soybean as well as the most current genetic map may befound in Soybase on the world wide web.

One use of molecular markers is Quantitative Trait Loci (QTL) mapping.QTL mapping is the use of markers, which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plant'sgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.

Production of Double Haploids

The production of double haploids can also be used for the developmentof plants with a homozygous phenotype in the breeding program. Forexample, a soybean plant for which 93Y10 is a parent can be used toproduce double haploid plants. Double haploids are produced by thedoubling of a set of chromosomes (1 N) from a heterozygous plant toproduce a completely homozygous individual. For example, see Wan et al.,“Efficient Production of Doubled Haploid Plants Through ColchicineTreatment of Anther-Derived Maize Callus”, Theoretical and AppliedGenetics, 77:889-892, 1989 and US2003/0005479. This can be advantageousbecause the process omits the generations of selfing needed to obtain ahomozygous plant from a heterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. The haploid induction systemcan produce haploid plants from any genotype by crossing a selected line(as female) with an inducer line. Such inducer lines for maize includeStock 6 (Coe, 1959, Am. Nat. 93:381-382; Sharkar and Coe, 1966, Genetics54:453-464) RWS (see world wide web sitewww.uni-hohenheim.de/%7Eipspwww/350b/indexe.html#Project3), KEMS(Deimling, Roeber, and Geiger, 1997, Vortr. Pflanzenzuchtg 38:203-224),or KMS and ZMS (Chalyk, Bylich & Chebotar, 1994, MNL 68:47; Chalyk &Chebotar, 2000, Plant Breeding 119:363-364), and indeterminategametophyte (ig) mutation (Kermicle 1969 Science 166:1422-1424). Thedisclosures of which are incorporated herein by reference.

Methods for obtaining haploid plants are also disclosed in Kobayashi, M.et al., Journ. of Heredity 71(1):9-14, 1980, Pollacsek, M., Agronomie(Paris) 12(3):247-251, 1992; Cho-Un-Haing et al., Journ. of Plant Biol.,1996, 39(3):185-188; Verdoodt, L., et al., February 1998, 96(2):294-300;Genetic Manipulation in Plant Breeding, Proceedings InternationalSymposium Organized by EUCARPIA, Sep. 8-13, 1985, Berlin, Germany;Chalyk et al., 1994, Maize Genet Coop. Newsletter 68:47; Chalyk, S.

Thus, an embodiment of this invention is a process for making asubstantially homozygous 93Y10 progeny plant by producing or obtaining aseed from the cross of 93Y10 and another soybean plant and applyingdouble haploid methods to the F1 seed or F1 plant or to any successivefilial generation. Based on studies in maize and currently beingconducted in soybean, such methods would decrease the number ofgenerations required to produce a variety with similar genetics orcharacteristics to 93Y10. See Bernardo, R. and Kahler, A. L., Theor.Appl. Genet. 102:986-992, 2001.

In particular, a process of making seed retaining the molecular markerprofile of soybean variety 93Y10 is contemplated, such processcomprising obtaining or producing F1 seed for which soybean variety93Y10 is a parent, inducing doubled haploids to create progeny withoutthe occurrence of meiotic segregation, obtaining the molecular markerprofile of soybean variety 93Y10, and selecting progeny that retain themolecular marker profile of 93Y10.

Use of 93Y10 in Tissue Culture

This invention is also directed to the use of variety 93Y10 in tissueculture. Tissue culture of various tissues of soybeans and regenerationof plants therefrom is well known and widely published. For example,reference may be had to Komatsuda, T. et al., “Genotype X SucroseInteractions for Somatic Embryogenesis in Soybean,” Crop Sci. 31:333-337(1991); Stephens, P. A. et al., “Agronomic Evaluation ofTissue-Culture-Derived Soybean Plants,” Theor. Appl. Genet.

No. 5,008,200, issued Apr. 16, 1991 to Ranch et al., thedisclosures of which are hereby incorporated herein in their entirety byreference.
